-the autofocus assist DOES NOT work with flashes, when you mount a sony flash and are using standard FE-mount lenses, the camera will still try and use its awful orange light instead of the much subtler red grid from the flash. AF assist light will not work at all with alpha glass.

-the back screen needs to be able to shut off rather then go black but still be powered. This is a waste of battery life and is just dumb. increase wake up speed and add in a faster sleep and the camera would almost be as efficient as a standard dslr with battery consumption.

-low light af is not good.

Please comment or add

Based on my previous experience with Sony, they rarely release any firmware update. The problem will probably get fixed in the next A9/R, and, of course, you have to pay again.
